This guy I know did a study at university one time for his PHD. His thesis was that different countries/cultures and races identified different things as "beauty". Not only did he set out to prove that simple thing, he tried to identify as many culturally biased beauty norms as he could, and then tried to ask why?
For example, for some African cultures big, big, women are thought to be the most beautiful. There are not alot of black guys here where I live but I do note they like the girls with lots (and lots) of "back", where as me and my friends like a little less...
In Germany, he proposed, attractive women are those who would be mothers of good soldures, so tall, athletic, perhaps big boned women.
I'm an North American Indian, should anyone want some pictures of good looking Native girls let me know, I like them tall, thin, with well defined features. If they like to phuck all the time thats good too.
So an objective question like this has no right or wrong answer, rather its a good exercise in realizing how many women are out there and that even though we may have our likes and dislikes, the next guy will prefer something else. With so many women out there, there has to be someone for all the fat ugly babes too. Go get 'em boys!!
